Very fun, well made game with a great art style and quite a unique mechanic! I just had a couple of small issues. First, you should be using the physical key locations as inputs rather than the character the key represents. It's a pretty easy tweak to make in most engines and makes your game easier to play on keyboard layouts other than qwerty. The other issue I had was that the first level that introduces the main mechanic doesn't really explain anything and it's kinda hard to figure out what you're even supposed to do at first. Once I got the hang of it, it was fine, but a bit more of a tutorial would have been nice. Still an amazing game overall despite those issues. Keep up the good work!
